TLC is a word about effort, not about money
That is what makes it slippery. Tender loving care sounds like weekends and a paintbrush. Deferred maintenance sounds like a bill, and it is the same house.
The useful translation is: something has not been done for a while. Your only job at the showing is to work out whether the thing not being done was decorative or structural.
Deferred maintenance has a shape you can see
It clusters. A house where the gutters are full is usually a house where the roof was not inspected either, and water that has been going the wrong way for years shows up at the bottom of the wall rather than the top.
- Full or sagging eavestroughs, and downspouts discharging against a foundation that slopes the wrong way.
- Moss, patches or curling on the roof, where a re-roof runs $8,000 to $18,000.
- A damp smell in the basement, which is the cheapest diagnostic you own and costs nothing to use.
- Foundation cracks that are horizontal rather than vertical, where sealing a minor one runs $500 to $2,000 and structural repair runs $5,000 to $40,000+. A horizontal crack is the one to take seriously.
What TLC does not usually mean
It is rarely used for a house with a genuine structural problem, because that is not something an agent describes as needing affection. If a listing is using TLC and the photographs are complete, the odds genuinely favour cosmetic work.
The three things worth more than everything else combined are the ones a photograph cannot show and that cost five figures to put right: the panel, the supply plumbing and the roof.
